Text in mobile version

Text in mobile version of my site is italicized and harder to read. Can I manage text in boll version?

I changed the text in my website to Hoefler text and it changed the text in the mobile version also.

Is that what you wanted?
It is important to style your text first so you can manage them across your chosen devices. In your case where you want the text style to be different per device you need to untick “Synchronise text attributes across devices”.
